Any issues going with a non-resistor plug using the HP EFI and DIS from Holley? Thanks.

You should use resistor type spark plugs with an EFI system, to suppress electrical noise/interference.Originally posted by Velocity540 View Post
(Unless it's a race only application and the non-resistor plug is the only heat range & dimensions available.)
Also, certain spark plug wires (such as FireCore50), transmit far less electrical interference than other
brands (low resistance and impregnated with ferrite molecular compound used to absorb RFI/EMI).

NGK also offers spark plug resistor caps to use with non-resistor type spark plugs:

You can also buy resistor boots from companies like NGK, that have the resistor built into them.
So you can run a non-resistor spark plug, but still get the RFI/EMI suppression of a resistor spark plug.
Some ignition coils, such as the LSx coils, don't like a non-resistor plug. The IGN1A coils do not care.
